non cingular sim card
Well, the sim card works just like any other sim card in a CINGULAR phone, but if you have the unlock codes to your other phone, I'm sure it will work.

Yes if your Razr is from Cingular or unlocked. You can not use a T-Mobile Razor with Cingular prepaid sim card or Globaltravellersim prepaid international sim card unless your phone is unlocked.
First, you would need to unlock the Sidekick. And make sure that the SIM card you're using is GSM-based. Now, once the Sidekick is unlocked, then you can use the phone for calling and texting only. You may not be able to use the data on your phone even if you register the phone for a data plan. Sidekick phones have special data plans that only T Mobile can support.
No
Technically speaking, a Cingular phone can be used with T-Mobile, as you only need to switch the SIM card. However, the phone may be locked to Cingular, in which you need to unlock it to be used with another GSM network.
